High Sulfur Sulfurized Isobutylene Content Additive EP Additives In Gear Oil

High-Sulfur Content Additive for Superior Extreme Pressure Performance T321

T321 Sulfurized Isobutylene is manufactured using a precision-controlled process involving isobutylene,

sulfur chloride, and sodium sulfide, with catalytic vulcanization and dechlorination.

Key features include:

• Extreme Pressure Resistance: High sulfur content (40%-46%) ensures superior wear protection.
• Oil Solubility: Light-colored and fully soluble, it blends seamlessly with base oils.
• Environmental Compliance: Low chlorine content (≤0.5%) aligns with modern regulatory standards.

T321’s versatility makes it suitable for gear oils, industrial lubricants, and formulations requiring phosphorus-nitrogen additives.
